Hello-OK so I recently got my Cold steel Kukri Machete. Sadly, it was subpar. The blade was missing paint, and the tip was blunt and irregular, and the edge was coarse and misaligned. (When I ran my fingers down one side of the blade, I could feel a "V" shaped ridge. There were also grease or oil stains on my machete. However, I don't want to return it. I want to fix it and make it a good chopper. Can you provide tips and info on how to sharpen it? All I have is a metal rod for sharpening knives, a Smith's pocket pal multifunction sharpener, and some sandpaper.
